Hi,

Is it possible for you to post your schematic?
It would help us to check other possible components that may cause the issue.

Thanks and regards!

Hi,

Which LT1819 is not working from your circuit?
What is your expected voltage level in each output of LT1819?

Also, I can see that you are using -3V/5V supply to your LT1819.
From your previous query, you have mentioned -3V/9V voltage supply.

Thanks and regards.
